SPECIFICATION forming part of Letters Patent No. 673,849, dated May 7, 1901. Application filed June 30, 1900. flerial No. 22,221. (No model.)

To all whom it may concern.

Be it known that we, CHARLES T. SoHoEN, residing at Philadelphia, in the county of Philadelphia, and JOHN M. HANSEN, residing at Bellevue, in the county of Allegheny, State of Pennsylvania,citizens of the United States, have invented a certain new and useful Improvement in Metallic Cars, of which the following is a full, clear, and exact description.

This invention has for its object to produce a metallic-car body the floor of which is practically free from rivets, so that in case of it being necessary to use shovels for unloading the car there would be no obstructions, such as projecting rivet-heads, to retard the work.

In carrying out our invention We use central sills of substantially L shape in crosssection and floor-plates of channel form or substantially Ll shape in cross-section and 20 rivet the flanges of these floor-plates to the upper flangeless edges of the sills and to the side plates. For the purpose of permitting uninterrupted passage of the inner flanges the body-bolsters are centrally depressed or dished.

In the accompanying drawings, illustrating our invention, in the two figures of which like parts are similarly designated, Figure l is a top plan View of a portion of a flatbottom 0 gondola car; and Fig. 2 is a cross-section thereof, taken centrally through the body-bolster.

The invention is illustrated as applied to the type of car shown in Patent No. 647,906,

datedAprill7,1900,andgrantedtothePressed Steel Car Company as assignee of the undersigned Charles T. Schoen. That car has no side sills, but has body-bolsters which extend continuously across the underframe and receive center sills between them and the inner ends of draft-rigging sills, the outer ends of the latter being supported upon the end sills and the side plates of the body being riveted to transoms projecting from the center sills and draft-rigging sills.

In the present invention the center sills a and draft-rigging sills 1), preferably of pressed steel, have bottom flanges c only-that is to say, they are of L-beam instead of channel form and their flaugeless edges (1 are uppermost. The floor-plates e andf are of channel or U formthat is to say, they have longitudinal edge flanges on both edges-and there are two series of such floor-plates, one, e, of a width to fit in between the center sills and draft-rigging sills,and the other,f, to fit in between the sills and the side plates g, and the flanges of the these floor-plates are riveted from below to the sills and are also riveted together with the side plates. By this construction there are no projecting rivets inside the car-body on the floor, and hence in the use of shovels for unloading the car the shovelers meet no obstructions to their work.

In order to permit the uninterrupted passage of the flanges of the floor-plates from end to end, the body-bolsters h have central depressions t-that is to say, they are dished.

It is advantageous to use corner-brackets at intervals, which are riveted to the floor- 70 plates and side plates and serve to reinforce and stiffen these parts at their juncture.

By using flanged floor-plates and riveting their flanges to the upper flangeless edges of the Webs of the sills these flanges serve as compression members for said sills.

Our invention is also applicable to those cars which have side sills and also to cars having underframes of various constructions other than those set forth.

What we claim is l. A metallic car, having sills extending centrally of the car and provided with flangeless upper edges, combined with floor-plates having longitudinal edge flanges riveted from below to said upper edges of the sills, substantially as described.

2. A metallic car, having side plates, sills extending centrally of the car and provided with flangeless upper edges, and floor-plates 9o flanged on their longitudinal edges and With their flanges riveted to the upper edges of the sills and to their side plates, substantially as described.

3. A metallic car, having side plates, centrally arranged longitudinal sills having flangeless upper edges, floor-plates flanged at our hands in presence of the subscribing witopposite sides and riveted to the side plates nesses.

and sills by their flanges, and corner-brack- CHARLES T. SOHOEN. ets riveted to the side and floor plates, sub- JOHN M. HANSEN.

In testimony whereof we have hereunto set W. H. SMITH.

It is hereby certified that in Letters Patent No. 673,849, granted May 7, 1901,

upon the application of Charles T. Schoen, of Philadelphia, and John M. Hansen, of

Bellevue, Pennsylvania, for an improvement in Metallic Oars, an error appears in the printed specification requiring correction, as follows: In line 93, page 1, the word their should read the; and that the said Letters Patent should be read with this correction therein that the same may conform to the record of the case in the Patent Office.
